Operating System Problems: Windows 7

Okay, I started off with a virus that corrupted my registry and operating system. The virus has been handled and there are no traces of it but it has left its lasting effect on my computer. I can not install some programs without it freezing my computer. (Example: Norton Antivirus, it will freeze as soon as it starts installing around 20%) I have been in the virus section for the last 2 weeks and they asked me to post here as there are corrupted registry files but he could not tell me which ones were corrupt or missing as well as possible operating system problems??? I am able to install things like Farbar, ESet antivirus installed properly, tdsskiller, but other programs like adobe , Norton, etc freeze my computer everytime.

Appreciate any insight and help I can get!

Not sure if it helps but this was the response from Virus team:

I had hoped that I could find a common denominator and suggest your reinstall a .net but all we found is the entries in the registry. No reference to what is missing or corrupted.

I have tried but the virus destroyed all of my restore options. It is a dell computer but it did not come with the recovery disk or windows 7, it does have a partition with recovery but it does not have a letter assigned to it so I was not sure how to restore from it without it being listed as a letter. It is blank where it showed have a letter. I have tried to restore from the files I could find but once it tried to restore it always says windows could not restore from this restore point. So I am at a loss as to what to do! I will start with repairing operating system!

Maybe using a tool like Kaspersky Recovery Disk 10, (works on any system and OS version). Takes forever but can at least get you inside and find the issue and repair it? Its used for virus, but I use it for repair so the system works again, which it does as well.

Following your description of the behavior & situation... do waste any time, effort or fuss. Do the following.

1st Recover this thing back to Factory Settings using Ctrl+F11

After it is up & running again do JUST the following:
1. Install MSEonly. Only ONE Security program!!
2. DL & install all Important Windows Updates.
3. Install CCleaner. Use it daily & only Run Cleaner
4. Other GOOD utilities to consider for Win7 are SpywareBlaster and Malwarebytes Both are free... select Manual Updating w/ SB & update it wkly.

Do not mess w/ the Registry nor have any 'Tools' messing w/ it, either.
